We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Not sure what your  truncated cone looks like. If it has round top tip, it might be a problem since it will need many more  tetrahedral grids. To resolve this, you may need to "cut" a little bit of the tip, say 5 nm.

If there is any small long gap, it might also cause this issue.

Adjusting the global mesh constraints or auto-refinement settings might help. More setting description can be found here https://optics.ansys.com/hc/en-us/articles/360034918633-CHARGE-solver-Simulation-object
